"r l BUMPER FOR MOTOR VEHICLES. 1

Application filed December 27, 1924. Serial No. 758,322.

To all whom it may concern:

Be it known that 1, CHARLES J.' Ivi;N, a citizen of the United States,and resident of Rochester, in the county of Monroe and g State of NewYork, have invented certain sists of certain parts and combinations ofparts, all of which will be hereinafter described: the novel featuresbting pointed 'out in the appended claims. I

In the drawings:

Fig. 1 is a plan view of a bumper'cohstructed inaccordance with thisinvention;

Fig. 2 is a face view of the bumper;

and p N Fig. 4 is asection on the line Fig. 1. In the illustrated"embodiment of the invention, there is provided an impact member formed,in this instance, from two strips 1 of flexible ribbon steel, saidstrips lying parallel'with each other and having their ends turnedrea'rwardly and toward each other, asst 2, to provide loops, the endsbeing connected together-by bolts 3.

The supporting means for this impact member, in this instance, is formedof ribbon steel and embodies a central portion 4 which lies inrear ot'the space between the two impact members 1. At opposite ends of thiscentral portion are formed the resilient.

supporting loops; Each of these resilient supporting loops embodies ahorizontally arranged U shaped portion 5, one arm of which connects withthe end of the central por- 59 tion t by a bond 6, the middle of thisarm lying in abutment with the rear face of the ventral portion and thenbeingideflect'ed at 7 so that it lies spaced from the central portion at8. This arm is provided with an opening which is coincident with an openTo these and other ends, the invention con- Fig. 3 is a section on thelined-3,- Fig.1;

ing adjacent the end of the central-portion t so thata bolt 9 may passthrough both openings. I This bolt 9-witl1 its nut l0,is utilized forsecuring thesupportingtmeans to the im pact member and to this endpasses through two clamping iiiembers 11 and 12. The clamping member 11lies inifront of the impact member and has rearwardly extending portlons13 extending respectively above and below the upper and lower bars ofthe impact member, the ends of these rearwardly extendin portions beingprovided with lugs 14 exten in toward each otherand on the rear faces ofthe impact member.v The other clamping member 12 has its, ends notchedat 15 to receive the projectingporticns 14., thereby causing theinterlocking-of the ends of the two clamping, pieces 11- and 12, thisinterlocking relation being held through the bolt 9, the member 12cooperating with the rear face of the impact member.

iThe other arm of theU shaped memlier 5 extends outwardly beyond thefirst mentioned arm and inrear thereof, its outer por-' tron beingprovided with a bend 16 concaved on its rear side and convexed on itsforward side 21nd,.the extreme end being secured to the impact member bythe bolt The at-' tachinp bracket 17, is secured to the rear arm 0 the Ushaped member 5 and to this end has a downwardly opening slot 18- inwhich the arm is held by a clamping bolt 19.

This bracket may be secfir'ed by the shackle bolt 20 to the lonitudinally extending frame bar 21 and by a holt 22 passing through theframe barin rear of the shackle bolt.

The supporting means is also seeured at its extreme center to the impactbar by a clamping means 23 which is somewhat simi-' lar to the clampingmeans ll and 12 which secures the supporting meansto the impact memberadjacent the longitudirial central portion 4, but differs due to thefact that only one thickness of the central portion 4; is present atthis point.- i

lVhile in the present embodiment t 'etwo springs of the supporting meansare connccted by a central portion, it is apparent that the invention isnot limited to this central connection.

From the foregoing it will be seen that there have been providedtwo-supporting 1 springs, each of which has a. portion extendingoutwardly from the attaching bracket to connect with an adjacent end ofthe impact member. this portion having a bend therein to facilitate themovement of the extreme end ot' the portion rearwardly when the end ot'the impact member is bent r zirvvarrlly. llach spring also has a springconnection between the attaching means and the impact member away fromthe end of the center of the latter, thereby permitting the flexing ofthe center and the end and providing a yielding support for the portionbetween the center and the end. The central connecting portion betweenthe two springs tends to strengthen the middle of the impactmember,while. at the same time, holding the two springs together so thatchattering noise is prevented, the space between the springs and thecentral portion being provided to prevent chat- .tering contact betweenthe two parts.

What 1 claim as my invention and desire to secure by Letters Patent is:

1 A bumper comprising an impact mem-- her, supporting means for theimpact member embodying a central portion and spring portions atopposite ends of the central portion, each having two arms lying in ahorizontal plane behind the central portion,

one of said arms being connected to'the central portion by a bend, andattachin means secured to the other arm of each spring portion.

2: A bumper compri'sin'gan impact memher supporting means for the impactmember-embodying a central portion and two arms lying behind the centralportion at each end of said central portion, one of said arms beingconnected to the central portion by a bend and-lying in abutment withsaid central portiornadjacent the bend, said arm also being deflectedaway from the central portion, and an attaching means connected to theother arm.

8. A bumper comprisingan impact member, a central portion secured to theimpact member, and a U shaped. spring having two arms, arranged in rearof said central portion at each end of said central portion, one of saidarms being longer than the other, the shorter armbeing connected to thecentral portion'by a bend and the longer arm being secured to the impactmember, and an attaching means also se cured to the longer arm. y

A. A bumper comprising an' attaching means, an im act member and twosubstantially U s aped springs, each having two arms, one of which islonger thant'he other, the longer arm having the attaching means securedthereto and extending on 0pposite sides of said. attaching means andmeans, the iree end of said longer arm being secured to the'inwardlyturned ends of the impactmember and being provided with a bend \whichwill permit the flexing of the impact member rearwardly and the shorterarm of the spring being secured to the impact member between the centerof the latter and an end.

6. A bumper comprisin an impact member, attaching means, and means forsupporting said bumper from the attaching 1neans,'said supporting meansembodying an arm extending outwardly from the attaching means andconnected with the impact member adjacent its end and an arm extendingoutwardly in advance of the first mentioned arm from a point on theinner side of the attaching means and connected with the impact memberbetween an end and the centencf said impact member.

7. A bumper comprising an impact member hait ing inwardly turnedportions at its ends, supporting springs for said impact memb'en'i eachhaving two arms extending in the same general direction, the inner ofsaid arms being longer than the outer one and being secured to theinwardly turned end of the impact, member and the shorter of said armsbeing secured to the impact member between the center of the latter andthe end, and attaching devices secured to the longer arm of each spring.

8. A bumper comprisin an impact member embodying two spaced bars, asupporting memberylyingin rear of said bars and means for securing theimpact member to the supporting member embodying two clamping platescooperating with the front and rear faces of the impact member, one ofsaid plates having notches in opposite ends and the other of s'aidplates having laterally turned portions engaging above and below theimpact member and provided with lugs extending into the notches of thefirst mentioned plate, and a bolt passing through both plates and thesupporting member.
